IMPROVED COMPOSITION FOR BUILDING MATERIAL.

TO ALL'WHOM IT MAY CONCERN:

'Be it known that I, SYLVESTER BISSELL, of Hartford, county of Hartford, and State of Connecticut, have invented certain'new and useful improvement in Composition 61- Building Materialyand to enable others=skilled injthe' art to makeand use-thesame, I ivill proceed to describe it.

The object of this invention consists in compounding or congcaling together bythe'useof suitable material,

ash draulic cemen nick-lime, fine particles of iron, as shavings or filings, with gravelpsand-in various proportions of about one-third more or less) each, and mixed with water.

I This composition is particularly adapted for window sills, \vin'dow'eaps, door caps, 8.10., especially where it is desirable to produce ornamental projections. It is only necessary top'repare moulds havingthe shape and configuration it'is' desired should appear upon the work; then prepare thecreqnired amount of composition in about the above-described quantities of each material, and mixed together with hydraulic cement, or with quicklime as asubstitute therefor; then pour the same into said moulds and lay away carefully to-dry. until perfectly hard; the longer it is left to harden the stronger it becomes. For large'work it should not be used for six or 5 eight weeks; I l

By the use of this invention I are enabled to produce a material or composition, the work from which will be less than one-fourthof the cost of stone, and which it is believed will be found to be equally strong and durable. I

I believe I have thus shown the nature, construction, and advantage of this invention so as to enable others skilled to make and usethe same therefrom.

I What I claim, therefore, and desire to secure by'Letters Patent, is-- I composition for building material, substantially as and in the proportions as described.
